## Description

3D NAND Technology for Enhanced Reliability and Power Efficiency Applying the advanced 3D NAND flash, Ace A55 features higher reliability and better power efficiency than traditional SSDs equipped with 2D NAND flash. The A55 offers improved endurance and longer battery life that you're able to work longer without frequently recharge your laptop. High Transfer Speeds for Fast Start Up Powered by high quality controller and original synchronous NAND flash, the A55 delivers incredibly high transfer speeds that enable short boot time, fast application loading and quick file processing. SLC Cache Technology for Performance Boost and Longer Lifespan The A55 especially applies the ”SLC Cache technology” that allows all data to be written in the SLC portion first and leads to higher peak writing performance. In addition, the technology can reduce write amplification and thus offer better endurance and longer lifespan of the SSD.
